Abstract: A method for processing volume image data obtains two-dimensional projection images of a subject on an image detector, wherein each of the images has the detector and a radiation source at a different scan angles. The image data is arranged as an image stack with corresponding pixel data from the detector in register for each of the images in the stack. A partial subset of projection images showing a metal object is identified. Information relative to the metal object propagates from the partial subject of projection images to the remaining images of the stack. For each of one or more stacked projection images, region growing defines a metal mask and adjusts image data values defined by the mask. The volume image data is reconstructed using region growing results. A 2D image is rendered and displayed from the reconstructed volume image data.

Abstract: A method acquires a reconstructed tomographic volume image of anatomy of a patient and constructs a primary axis for a bone of interest in the imaged anatomy. The method forms a sectioned image of the bone in the volume image according to a first plane that is defined to extend along the bone and to extend through two or more articular surfaces. A primary axis for the bone is estimated, wherein the primary axis is midway between outer edges of the bone image that intersect the first sectioning plane. The bone is sectioned in the volume image by a second plane that is orthogonal to the first plane and that extends through the estimated primary axis. The method recalculates the position of the constructed primary axis according to the sectioning of the bone by the second plane. The recalculated constructed primary axis for the bone of interest is displayed.

Abstract: A method for rib suppression in a chest x-ray image of a patient. The method detects and labels one or more ribs in a region of interest in the x-ray image that includes a lung region. The method obtains a rib model for one or more ribs of the image and modifies detection results for the one or more ribs by applying the rib model in the region of interest. A conditioned x-ray image is formed by suppressing rib content according to the modified detection results. The conditioned x-ray image is stored, displayed, or transmitted.

Abstract: An X-ray image quality control system includes an image acquisition unit configured to acquire an X-ray image and determine the type of imaged body part and the type of projection mode. A quality detection unit is configured to detect an image defect in X-ray image with regard to the type of the imaged body part and/or the type of the projection mode. The quality control system effectively identifies image defects including inaccurate positioning, patient movement, external object artifacts, and poor exposure. The system provides feedback to the technician at the image acquisition point to adjust the image acquisition solution in a timely manner.
